It is contemplated that the driving device further includes a driving motor for driving the carrying cylinder 132 to rotate, which is prior art and will not be described herein. The stationary core 131 is relatively fixed with respect to the carrier cylinder 132, i.e. it does not rotate with the carrier cylinder 132. The carrying cylinder 132 is used for carrying the rotary base 12, and when the carrying cylinder 132 is driven by the driving motor to rotate, the rotary base 12 is driven to rotate together.

The winding device 20 includes a three-dimensional threading mechanism 21 disposed on the table of the frame 10, at least one set of winding dies 22 disposed on the rotary base 12, and a thread pressing device 23 disposed on the frame 10. It is contemplated that the winding device 20 may further include other functional modules, such as a clamp release mechanism, a driving motor, a coil dividing block, and an accessory module, which are well known in the art and will not be described herein. The three-dimensional threading mechanism 21 is used for moving the wire X, Y, Z in three directions to feed the wire into the winding die 22, specifically into the thread-lifting clamping mechanism of the winding die 22. The structure of the three-dimensional threading mechanism 21 itself should be the prior art, such as a motor, a screw, etc., and will not be described herein. The winding mold 22 includes a tail wire clamping mechanism, an unlocking mechanism, a winding table, a coil dividing block, a motor, etc., which are prior art and will not be described herein. The wire can be wound into a coil while the winding die 22 is rotated.

The driving motor 224 is used for driving the bobbin 223 to rotate, and the rotation direction and speed of the bobbin 223 are the same as those of the winding table 221.

The motor 232 drives the screw 233 to rotate so as to drive the nut seat 234 to move. When the nut seat 234 moves, the wire pressing disc 235 can be inserted between the winding table 221 and the wire ejecting disc 223 and abut against the just wound wire, so that the accuracy of the wound coil in the radial direction can be ensured. The wire compression disc 235 is rotatably disposed on the nut seat 234. When the radial diameter of the wound wire is larger and larger, the coil abuts against the wire pressing disc 235, so that when the thrust force applied to the nut seat 234 is larger than the torque of the motor 232, the nut seat 234 drives the screw 233 to rotate in the direction opposite to the output torque of the motor 232, and the wire pressing disc 235 moves away from the coil. After the winding of the coil is completed, the next step is to attach the mica sheet, so that the rotary base 12 drives one set of winding dies 22 around which the coil is wound to enter the next station, and the other set of winding dies 22 is brought into the winding station to enter the winding.
